Weathering, Erosion, Deposition

Front

What is Weathering?

Back

Weathering is the process of breaking down rocks and minerals into smaller pieces by natural forces such as wind, water, and temperature changes.

Front

What is Erosion?

Back

Erosion is the movement of weathered materials from one location to another, often caused by water, wind, or ice.

Front

What is Deposition?

Back

Deposition is the process where sediments, soil, and rocks are added to a landform or land mass, often occurring after erosion.

Front

Example of Weathering:

Back

Water getting into cracks, freezing, and breaking rocks apart.

Front

Example of Erosion:

Back

A mudslide flowing down a steep hill.

Front

Example of Deposition:

Back

Sand being deposited at the mouth of a river.

Front

What causes Weathering?

Back

Weathering can be caused by physical factors like temperature changes, water, ice, and chemical reactions.

Front

What are the types of Weathering?

Back

There are two main types of weathering: mechanical (physical) weathering and chemical weathering.

Front

What is Mechanical Weathering?

Back

Mechanical weathering is the physical breakdown of rocks without changing their chemical composition.

Front

What is Chemical Weathering?

Back

Chemical weathering involves the chemical alteration of minerals in rocks, often due to reactions with water or acids.
